I just checked Microsofts site and it only has SP1 available as of now.

... Thank you ... I am so dumb sometimes.

Hi Got my new pc today ... installed FSX, SP1 and Flynet ... booked myself a flight, jumped in cockpit, Alt-Tabbed, started FlyNet .. it got my flight.... but then said that FSX wasnt running, which it was cos Id minimised it ... so I reinstalled everything ... tried again .... same thing ...
